Matthew Poole and continuators on Numbers 23:13

13 And Balak said unto him, Come, I pray thee, with me unto another place, from whence thou mayest see them: thou shalt see but the utmost part of them, and shalt not see them all : and curse me them from thence.

He thought the sight of the people necessary both to excite Balaams passions, and to strengthen and direct his conjurations, but he would now have him see but a part of the people and not all, because the sight of all of them might dismay and discourage him, and, as it did before, raise his fancy to an admiration of the multitude and of the felicity of the people, ver. 9, 10.
